Differences between the LED and halogen diving lights

This instructional video by Scuba.com explains the difference between the two major types of lights. They are the Halogen (Xeon) and LED. The Halogen has a single glass bulb just like any other light we are used to seeing and the LED light has a diode with no glass involved. The significant difference between the two is that the LED is much more durable and the light is a different spectrum. It is more of a white light unlike the halogen that has a yellow light. The LED also has a longer burning time than the Halogen bulb too. The major advantage to an LED light is the amount of battery life you get. If you change your batteries three times with LED light you will end up changing your batteries nine times with halogen lights. Although the LED is about three times as much, in the long run you will save more money on batteries and bulbs.

We're staring to compare Semi trucks to skate boards here. Cree makes a great product, but they don't make them for scuba applictions, so the point is moot. Maybe one day they'll make a bulb for smaller, handheld applications but until that time some of the best performing lights for divers would be the UK Aquasun light or maybe the L.E.D. lights from Big Blue. Both are remarkably brighter than other similar sized hand held diving lights and will offer you years of service!

@scubacom

Any CREE Led can be adopted for underwater use. It has been done, and is being done.

[scubacom]

@lazerusmfh Yes, that is true. And in a pinch I once filled a normal flashlight that the Air Force issued me with silicone grease and got it to work for a dive as well. But, adapted for use and commercially and readily available are different things. Cree makes amazing products but at this time for the average recreational diver we are still talking a product not readily available or within most budgets.

and uhh.. there isn't nearly the same projection with the LED as there is with the Xeon. So... Xeon or HIDs it is.

The L.E.D. lights are constantly improving. The UK AquaSun Rechargeable eLED is one the best LEDs out there and is giving the HID lights a run for the money. 026613

@scubacom Really....... I would love to see a led come close to a hid globe. If I could replace my hid spot lights on my car for led's I would. AquaSun hey......i'll check it out

@ZmannR2 I don't have the knowledge to use my big 12 volt battery pack with LED's. I know I ought to be able to use some kind of step down, but then - am I still getting full use from the batteries? I don't know. The batteries that seem to work best with the bright LED's don't have the run time. I guess I can put them in parallel right? But, then I have to start over with the cost of new battteries and take the time to build a new case. So for now, I'm happy being super bright 20 watt halogen.

@ZmannR2 2 things: First, for me as a bicycle rider, YES run time IS the main thing and 2. I don't think I was talking about that. My halogen system was cheap and easy to build is still brighter than most LED's, even the ones that claim to be brighter (total output and wide spread) and the battery pack I matched to it lets me run 3hrs which is more than I need for most rides. Now - it will be very nice when I get an LED setup and gain the longer run time. But it's not apples vs apples.

@jcisbell the bulb isnt the point......its battery life...period

I don´t know what you mean by "projection" and I don´t know what´s "Xeon". Maybe you don´t know the newest news from LED industry but Luminus made a single LED with output up to 6000 lumens. It´s more that you can get from a 50W HID bulb. So, you can have extremely powerful light from one little LED. It´s reality now. The time of HIDs is almost over.
